Strongly agreed. A nice thing about the current spec files in
Fedora-land IMHO is that they are easy to read and to understand, even
if you look at them for the first time.

That's IMHO often not the case for some spec files out in the wild that
use conditionals quite heavily. Heavily IMHO = all those with more then
three --with/--without or other conditionals.
